Abstract
Ink jet apparatus for utilizing hot melt ink is provided, comprising a printing head and a reservoir for holding a supply of hot melt ink, the reservoir having a normally open port or fill tube with an end face residing within the volume of the reservoir, the end face being located at about the volumetric center of the reservoir. The reservoir is maintained with an ink volume of no more than about half of the reservoir volume, so that ink can not spill through the normally open port when the apparatus is tilted.
